Abstract
The invention discloses a fire-proof transformer. The fire-proof transformer comprises a coil frame for winding coils, a magnetic core arranged in the center through hole of the coil frame, a refractory transformer shell, vent holes formed in both sides of the refractory transformer shell, rotatable enclosing assemblies which are arranged beside the vent holes and are used for enclosing the vent holes, and a temperature sensor which is arranged in the refractory transformer shell. By adopting a refractory enclosing cover which can be used for enclosing the coils, a sealed space can be provided for the coils in case of fire. Since oxygen is not supplied to the coils, combustion cannot be maintained, thereby realizing extinguishing and avoiding safety accidents.
Description
Technical field
A kind of electric equipment, particularly a kind of transformer.
Background technology
Mainly there is such form according to the transformer of prior art: primary coil and secondary coil are sequentially wrapped on single coil frame, and core is attached to bobbin by the through hole of bobbin.For fear of electric leakage or other accidents; conventionally can between magnetic core and bobbin, insulation cushion be set; but magnetic core can generate heat at work; impel the aging of insulation cushion, coil also can generate heat, heat accumulation; impel coil aging; thereby cause Local Fire, security incident occurs, prior art is unresolved such problem also.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a fire resistant seal layer, its material is incombustible refractory material, and the environment of a sealing can be provided for coil when breaking out of fire, stops the generation of fire, avoids occurring security incident.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
Fire prevention transformer, comprise: the bobbin of winding around, be placed in the magnetic core in bobbin central through hole, fire-resistant transformer case, be located at the ventilating opening of fire-resistant transformer case both sides, be located at the closed component of the other rotatable and enclosed ventilation mouth of ventilating opening, be located at the temperature inductor in fire-resistant transformer case.
Aforesaid a kind of fire prevention transformer, closed component composition has: be fixed on the rotating part on fire-resistant transformer case, be connected in the closing cap of rotating part, cover on above-mentioned closing cap and contact the sealant of ventilating opening.
Aforesaid a kind of fire prevention transformer, rotating part is electric rotation shaft.
Aforesaid a kind of fire prevention transformer, sealant is rubber layer.
Aforesaid a kind of fire prevention transformer, the material that fire-resistant transformer case adopts is thermosetting resin-impregnated paper high-pressure laminated board.
Aforesaid a kind of fire prevention transformer, ventilating opening place is provided with anti-hawk.
Aforesaid a kind of fire prevention transformer, anti-hawk is web plate.
Usefulness of the present invention is: the invention provides a kind of fire-resistant closing cap that can encapsulated coil, the space of a sealing can be provided for coil when breaking out of fire, and coil, owing to not having oxygen to supply with, cannot maintain burning, thereby realize fire extinguishing, avoid occurring security incident.
Brief description of the drawings
Fig. 1 is the sectional view of a kind of embodiment of the present invention.
The implication of Reference numeral in figure:
1 bobbin, 2 closing caps, 3 sealants, 4 rotating shafts, 5 transformer cases, 6 temperature inductors, 7 anti-hawks, 8 ventilating openings.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Fire prevention transformer, comprise: the bobbin 1 of winding around, be placed in the magnetic core in bobbin 1 central through hole, fire-resistant transformer case 5, the ventilating opening 8 of fire-resistant transformer case 5 both sides, the rotatable also closed component of enclosed ventilation mouth 8 that ventilating opening 8 is other, the temperature inductor 6 in fire-resistant transformer case 5.
Closed component composition has: being fixed on the rotating part on fire-resistant transformer case 5, is electric rotation shaft 4 as preferred rotating part; Be connected in the closing cap 2 of rotating part, cover on above-mentioned closing cap 2 and the sealant 3 that contacts ventilating opening 8 is rubber layer as preferred sealant 3; The material that fire-resistant transformer case 5 adopts is thermosetting resin-impregnated paper high-pressure laminated board.
Fire prevention transformer ventilating opening 8 places are provided with anti-hawk 7, and its material is web plate.
If the overheated burning of coil or magnetic core, cause transformer internal temperature too high, temperature inductor 6 senses that temperature is higher than set point, by communication, to controller, controller can be realized as long as Programmable Logic Controller herein, and controller control motor-driven rotatable shaft is rotated to ventilating opening 8 positions, form seal cavity, coil, owing to not having oxygen to supply with, cannot maintain burning, thereby realizes the object of fire extinguishing.
More than show and described general principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
